FOREVENTonsubmit() event handler for the object whose ID is myform:
<SCRIPT TYPE="text/javascript" FOR="myform" EVENT="onsubmit()">
<!--
var response=confirm("are you sure you want to submit?");
return response;
//-->
</SCRIPT>
The script is then applied to a form by setting the form's ID to
myform:
<FORM ACTION="../cgi-bin/mycgi.pl" ID="myform"> name: <INPUT NAME="realname"><BR> email: <INPUT NAME="email"><BR> <INPUT TYPE=SUBMIT VALUE="join"> </FORM>
which (in MSIE) gives us this form:
This technique for setting an event handler isn't any easier than the traditional method which is also much more universal. Any object that has an event can have that event set with the appropriate attribute. For example, to set our form to check if the user really wants to submit we can use a script function and the
onSubmitsubmitconfirm():
<SCRIPT TYPE="text/javascript">
<!--
function submitconfirm()
{
var response=confirm("are you sure you want to submit?");
return response;
}
//-->
</SCRIPT>
The form would call submitconfirm() in
onSubmit
<FORM
ACTION="../cgi-bin/mycgi.pl"
onSubmit="return submitconfirm()">
name: <INPUT NAME="realname"><BR>
email: <INPUT NAME="email"><BR>
<INPUT TYPE=SUBMIT VALUE="join">
</FORM>
which gives us this form (try submitting it):
